Genetic Analyses of the Yellow-Veins Mutant in Cotton.

Eight virescent and morphological mutants were found in a cotton (Gossypium hirsutum L.) breeding nursery at College Station, Tex., in 1962. Four of those mutants were conditioned by the same recessive allele. The mutant was named yellow-veins and assigned the symbol y. The phenotype of the mutant is described as is variability associated with expression of the trait. Analyses with 38 other mutant loci provided evidence for linkage of y with Rugate (Ru) and virescent-1 (1) to establish linkage group XVII, Ru-37-y-30-1.
